Feeding your puppy only from hollow chew toys rather than a bowl will have an immediate and enormous positive effect on your puppy’s behavior and temperament. Bowl-fed puppies often become overly excited prior to meal times and gobble too much food at one time, which is decidedly unhealthy. On the other hand, chew toy-fed puppies are less destructive, quieter, calmer and less likely to get bloat or develop separation anxiety.
